詳細描述

QPressureReading Units

The pressure sensor returns atmospheric pressure values in Pascals.

特性文檔編製

`[read-only]` pressure : const qreal

This property holds the measured atmospheric pressure.

Returned as Pascals.

`[read-only]` temperature : const qreal

This property holds the pressure sensor's temperature.

The temperature is returned in degree Celsius. This property, if supported, provides the pressure sensor die temperature. Note that this temperature may be (and usually is) different than the temperature reported from QAmbientTemperatureSensor 。使用 QSensor::isFeatureSupported () 采用 QSensor::PressureSensorTemperature flag to determine its availability.
